barrel tilts downward from its locked position, permitting full recoil of the slide
and the extraction and ejection of the spent cartridge case.

is closed and the slide is then retracted fully, the slide stop will not automatically
hold open the slide. The user can actuate the slide stop mechanism to hold the
slide open at any...
